International charity group, Oxfam, has criticized the group of seven rich countries for their poor contribution to efforts to inoculate the world against Covid. G7 members are set to begin a three-day summit on Friday. They are expected to agree to donate one billion Covid vaccine doses to poorer countries. That’s according to the UK government. Now, Oxfam and other campaign groups have condemned the plan as a drop in the ocean. Oxfam says, the summit will be a failure, if the best G7 leaders can manage, is to donate one billion doses. It says the world would need eleven billion doses to end the pandemic. Oxfam has also called on G7 leaders to support a waiver on the intellectual property behind the vaccines.
